Similar numerals of reference indicate like parts tnrouglioutl theseveral views on the drawings.

Referring now to the details of the drawings the numeral 1 indicatestlie wall or partition of the tellers cage inr which tlie usual gratedWindow 3 adjacent thereto. Numeral 4 indicates a movable` shutter ordoor for closing the grated windowv 2, and numeral 5 indicates a springroller curtain connected With the shutter 4 adjacent one edge ci thelatter for screening the or Utransparent window (not shown) located inthe Wall 1 behind the shutter 4 when the latter is retracted to disclosethe window 2. f

Numeral 6 indicates the tellers cage entrance door which is slidablymounted in the partition 1 in any suitablev manner, but preferably onrollers, as herein described, said rdoor being adapted to be actuatedsimultaneously with or independently oi the shutter door 4,as'hereinafter described.y Thenumeral 7 indicates a trap unit foractuating both the shutter 4 and the door 6 when thev two aredisengageably connected together, or the shutter door 4 alone when thedoor 6 is closed the former is to be closed over the windowV 2. Numeral8 indicates the second trap unit which is adapted to close only the door6 independently of the shutter door 4. Both of the trap units 7 and 8are alike in mechanical details and only one of them will be describedherein for that reason.

The numeral 9 indicates the cable for actuating the shutter door 4 andwhich is connected with the latter at l0, said cable being trained oversuitable rollers or pulleys lland l2 to lconnect the end thereof withthe'counter weight 13, the latter being arranged within the trap unit 7,or

8, the latter including a suitable apertured casing to admit the cable 9thereto. The numeral 14 indicates a flexible cable for closing the door6 and it is connected with said door at 15 and trained over the pulleysor rollers 16, 17 and 18, thence into the trap unit 8 where it isconnected with a counter weight 13 in said unit. The roller 16 ismounted on the partition l ahead of the cable anchorage 15 to effect thenecessary draft on the door for closing the latter which follows thefall of the weight 13 in the trap unit.

The shutter 4 is carried upon the roller trucks 19 and 19 which operateupon the horizontal double track bars 26 and 2l which have theirextremities mounted in the brackets 22 and 23 carried by the partition1, and the door 6 is operable upon said track bars by roller trucks 24and 25. Both the shutter 4 and door 6 are arranged between the trackbars 20 and 2l which are sufficiently close together to maintain thejuxtaposition of the members 4 and 6 there-between. Preferably, thetrack bars 20 and 21 are made of flat metal to facilitate the engagementof the roller trucks 19, 19 and 24 and 25 therewith.

The numeral 26 indicates a horizontal abutment bar connected with thepartition 1 and arranged in front of the shutter 4 and grated window 2to prevent unauthorized inward tiltable displacement of the shutter 4 ineither the open or closed position thereof.

The numerals 27 and 28 indicate two pairs of abutment rollers suitablymounted in the shutter door 4 below the track bars 20 and 21 and spacedtherefrom suitably to admit of limited upward displacement of theshutter 4 and rollers 19 and 19', said rollers being adapted to engagethe under side of the track bars when the shutter is upwardly displacedfor any reason, as by an obstruction beneath said shutter when thelatter is in motion. Similarly, the door 6 is provided with a pair ofabutment rollers 29 and 30 below and spaced from the track bars 20 and21 and which are adapted to engage said tracks upon upward displacementof the door 6 and to function as stop elements.

Numeral 31 indicates a traction bar disengageably connecting the shutterdoor 4 with door 6 and rigidly connected with the former at 32. Theouter end of the traction bar 31 carries an enlarged head or knob 33which is engageable with a furcated abutment member 34 xedly connectedwith the top end of the door 6, said bar being displaceable upward outof engagement with the furcation of the member 34 to release the door 6from the bar knob 33 to enable independent movement of said door. Whenthe bar 31 is thus displaced from the member 34 it is caused to engagethe furcation 35 of the furcated member or bracket 36 which ispositioned above the member 34 and rigid with partition 1, whereby theknob 33 is caused to engage the face of member 36 disengageably lockingthe shutter 4 against closure movement, as is hereinafter described.

The numeral 37 indicates a yieldably mounted wall section of thepartition 1 and arranged between the track bars 26 land 21, the upperend whereof is carried upon the two pairs oi roller .trucks 38 and 39which operate upon said track bars similar to the function of rollers 24and 25 of door 6.

The partition wall section 37 carries also the abutment rollers 40 and41 below and spaced from the track bars 20 and 21 which function toengage said track bars to limit upward movement of the wall section 37when the latter may be upwardly displaced for any reason. The numerals42 and 43 indicate compression springs which encompass the carrier andguide rods 44 and 45, respectively, which are rigidly connected with thewall section 37, said rods having their ends slidably and tiltablyengaging in suitable apertures 48 formed in the guide brackets 46 and47, respectively, rigid with the partition 1. The wall section 37 isadapted to function as a yieldabie abut ment for the door 6 when thelatter is closed upon any kind of an obstruction of limited volumeinterposed between the edges of said door and said wall section.

Means for positively locking the wall section 37 against yieldingmovement is provided and may comprise a bell-crank 49 tiltably mountedon said wall section at 50, a vertically arranged and slidable lockingbolt 51 connected with one arm of said bell-crank, and a bell-crankactuating pin 52 which is slidably and horizontally arranged in theguide bracket 53, the point of said pin being engageable by a hammerblock 54 rigidly mounted on door 6 adjacent the edge thereof. 51 isdisengaged from a bolt socket 55 formed in track bar 26, and will dropfrom said socket when subject to no urge, said bolt being forced intosaid bolt socket only when the block 54 forcibly engages the point ofthe pin 52, the latter being operatively connected with the second armof the bell-crank 49. n

In the event an obstruction is interposed, for any reason, between door6 and wall section 37, when the former is forcibly closed, or actuatedfor closure, it then becomes impossible for the hammer block 54 toengage or actuate the pin 52, whereby the said wall section will yieldto the right against the springs 42 and 43, as indicated in dotted linesthereof. 1f the obstruction referred to were a mans hand or arm seriousinjury thereto would thereby be averted.

As heretofore stated the trap units 7 and 8 are alike in mechanicaldetails and only one of them will therefore be described. Numeral 56indi 1 cates the trap unit casing within which the counter weight 13disposed for operation when connected with the cable 9. 'When elevated,the weight 13 is supported upon the inner end of a supporting lever 57which is pivotally mounted in a pair of opposed bearing brackets 58 and59 exteriorly of the casing 56, said supporting lever being held in anormally horizontal position by a trigger element 66 which isdisengageably locked thereto by a notch element 61, said trigger elementbeing pivotally mounted on a shaft 62 which is carried in the brackets58 and 59. The supporting lever 57 may be provided with opposed trunnionpins 63 and 64 (Fig. 3) to provide the desired pivotal support thereforin the brackets 58 and 59.

The inner end of the lever 57, upon which the weight 13 normally iscarried, may be furcated at 66 with a roller 67 mounted in saidfurcation,

the opposite end of said lever projecting through.A

an opening formed in the wall of the casing 56. Numeral 68 indicates acurved pick-up arm secured to the bottom of the weight 13 by screws, orotherwise suitably by fastener members 69, said curved arm beingarranged within the lever furcation 66, the point thereof extendingbeyond the roller 67 toward the medial portion of said lever and incontact with the roller 67.

The numeral 79 indicates a link operatively connecting the upper end ofthe trigger 60 with Normally, the point of the locking bolt lli) o rweight tilting the lever 57 to a ho" foot ietf-.al 30 m unted thereon torock said sliaft.y

Obviously, when pedal S is depressed, t e trigger 60 tilted away fromthe cas'flg thereby disengaging notch 6l point of the suppe. lever 51,thereby releasing the weight 3 of trigger control weight to fall to thebottom oi the casing 56, whereby shutter 4 is actuated and window 2closed thereby. Simultaneously the curtain 5 is caused to be uni-oiledand to screen the glass window exposed by the cle. re movement of saidshutter 4. The fall of the 13 tilts the supporting lever 57 to anupright position and the weight ol the parts causes the tagger 60 totilt toward the casing 56 to an inclined position and leaning againstthe upper end of the lever 57, in which relation parts are at rest. Uponelevation oi the v eight 13 by the electric motor, or other-- wise,as'hereinafter described, the point of the weight arm which projectsthrough casing opening 65, r picks-up the roller 67 in the leverfurcation continued elevation of ontal position and causing the outerend of said lever to again engage the notch 61 of trigger 63 which been'tilted outward by said lever. ln such movement of the parts describedthe ner end of the lever 57 again functions as support for the weight13, as is apparent, which is then releasably locked thereon.

The elevation of the weight 13, as described, also rocks shafts 72 and78, and the levers and members carried thereby, to their formerpositionswhereby depression of the pedal v will again cause the fall ofthe weight 13 with the results as described. From theforegoing it willbe evident, if the door 6 is open and rod 3l is operatively connectedtherewith by bracket 34 and knob 33, that the fall of the weight 13 willnot only actuate shutter 4 and curtain 5 but also effect closuremovement of the `door 6. rind it will also be evif dent,` if the door 6is closed on that occasion, that vits closure movement, upwarddisplacementof the shutter will occur when it contacts with any suchobstruction which may be thrust through the grated windowi adjacent thedesk 3, and whereby the shutter 4 will glide over such obstruction andfully close said window. And in such upward displacement of the shutterdoor the roller trucks 27 and 23 will limit the upward movement of saidshutter door. In the event any ordinary obstruction is interposed belowthe door 6 the rollers 29 and 30 will admit of limited upwarddisplacement of said door, enabling the full and complete closure ofsaid door. And similarly, rollers and 4l will admit of limited upwarddisplacement of the wall section 37.

The trap unit 8 may be operated in any suitable manner to release theweight 13 therein for closing the door 6, but, as illustrated, a leverarm 84 is utilized for that purpose, said lever being rigidly connectedwith the rock-shaft 72 in said trap unit, as a substitute for the lever75 shown in Fig. 2 of trap unit 7, and when the lever 84 is swung upwardby the operator the weight 13is thereby released and actuation of thedoor 6 follows such release.

Motor means is provided for opening shutter 4 and door 6, and such meansmay take the form of an electric motor 85 mounted on a suitable bracket86, the motor drive shaft carrying a spur gear 87 which meshes with aspurv gear 86, the latter being carried on a bearing pin 39 projectingfrom a lever arm 90, said lever arm being pivotally carried .at 91 in abracket 92 supported on the motor bracket 37. The lever arm is providedwith a handle 93 projecting laterally therefrom, whereby the gear 88 maybe manually swungupward and downward and into and out of mesh with atoothed element 94 which is provided on the horizontal door actuatingbar 95, the latter having one end thereof rigidly connected with thedoor 6. The bar 95 carries also a depending knock--of cam 96 which isadapted to engage the gear 83 to demo-sh Asame from the rack 94 when thedoor 6 and shutter 4 have been'fully opened and both weights 13 in.units 7 and 8 have been elevated latched in position. Normally, the gear33 is disengaged from the rack 94 by the weight of the handle 93.

When desirable, the cables 9 and 14 may be locked against movement eventhough the weights 13 may be free to fall, such locking devicescomprising a locking box 97 for each cable, which box is traversed bythe cable which is normally free to move therethrough, in eitherdirection.

Each of the cable locking boxes 97 is provided with an L shaped lookinglever 93 pivotally mounted ytherein at 99, the lower end or point 160whereof may be swung into and out of engagement with the cable, at thewill of an operator, whereby, when so'engaged with the cable, draft oncable, which would tend to close the door 6 shutter 4, causes Ythe point100 to force the cable against the wall or? the boi; Q7 and locking thecable rigidly against draft.

Mechanism is provided for opening the 6 independently of shutter 4 andfrom either the interior or exterior of the tellers cage. Such a meanscontemplates a lever 101 which is pivot 'lv mounted in a oor bracket orbearing 162 intermediate the lever extremities, the bracket 102 beingmounted within the tellers cage, preferably, and said lever beingprovided with a late eral pedal 103 which projects through a suitableopening in the partition 1 lto the exterior of the cage. As heretoforestated, the door actuating bar 31 is provided with a knob 33 whichnormally engages the iurcated bracket 34 on door 6. And it has also beenshown that the bar 31 is movable upward to cause the disengagement ofthe bar knob 33 from the bracket 34, and such upward displacement of thebar 31 is effected by a forked lever 104 mounted on the rock-shaft 105,said bar 31 traversing the furcation of said forked lever, and said rockshaft being mounted in suitable brackets 106 and 107 and r ckable by alever 108 and a link 109, vthe latter operatively connecting the pedallever 101 with the rock shaft lever 108. Obviously, depression of thepedal. 103, positioned outside of the partition 1, will rock the shaftand disengage the bar 31 from bracket 34 and elevate said bar into thefurcation 36 of the bracket 36, thereby releasing the door 6 from theabutment knob 33. The same effect may be provided or produced byactuation of the lever 101 which is accessible adjacent the point ofconnection with the link 109.
